针对铁氧体的高精度环形金刚石线锯切割工艺参数优化问题，以其切割后的面形精度和表面粗糙度作为评价指标，采用正交试验法研究主轴转速、进给速度和张紧力等工艺参数对切割表面质量的影响，并基于灰色理论对多工艺目标进行数据分析和综合评判，得到工艺参数组合优化方案为：主轴转速，1 000 r/min；进给速度，1.0 mm/min；张紧力，90 N。切割试验结果表明：用优化后的参数组合得到的面形精度PV为7.37μm、表面粗糙度Ra为0.882μm，加工表面质量提高，验证了铁氧体切割工艺参数优化的有效性和实用性。

Parameters optimization for ferrite slicing based on grey theory

To optimize the parameters of slicing ferrite with high precision diamond ring saw, an orthogonal test is designed with the fabricating surface accuracy and the surface roughness as evaluation indicators and the spindle speed, the feed speed and the tension force as factors. Based on the grey theory, the data analysis and the comprehensive evaluation of the multiple process targets are carried out to obtain an optimized process parameter combination, namely the spindle speed 1 000 r/min, the feed speed 1.0 mm/min and the tension force 90 N. The slicing test results show that the optimized parameter combination can obtain a surface accuracy of PV 7.37 μm and a surface roughness R_a of 0.882 μm, and the slicing surface quality is improved, which verifies the effectiveness and practicability of this method in the optimization of ferrite slicing process parameters.
